Abstract

The present invention relates to a process for preparing copolyesters which involves two steps. The first step is a diol interchange step, and the second step is a polycondensation step. More specifically, the process involves (I) reacting in the presence of a polycondensation catalyst a dihydroxy terephthalate-containing compound having the formula: <IMAGE> wherein n is 1 to 10 and at least 99% of the endgroups are ethylene glycol moieties; and 0.01 to 10 moles, based on moles of the dihydroxy terephthalate-containing compound, of a diol, and (II) polycondensing the reaction product of Step (I) to form a copolyester while excess diol is removed until desired molecular weight is obtained. This process does not include a transesterification of a dialkyl ester reaction or an esterification reaction which are usually used to produce copolyesters. Moreover, this process allows for polyethylene terephthalate and copolyesters prepared therefrom to be produced on an integrated production line.
